it known that we, Tic-RANK ivi. PETERS `and lVAnnnN H, Honennrono, bothcitizens:

of the United States, residing` at Chicago, in the county of Cook' andState of illinois, have invented certain new and usefullniprove-ments inDough-tjheeting Apparatus, of which the following is a specification. l

Our. invention has reference to dough sheeting` apparatus, and hasparticular application to apparatus for n'iaking sponge dough, i. e.,dough in which the rolling must be effected in two directions at anangle to each other. The invention is also of spe-- cial value inconnection with machines for roilingi` eithersponpe dough or sweetdough. i. e., dough used for cakes or cookies, and which' does not`require cross-rolling.

The principal objects of the invention are to provide an improvedmachine in which cross-rolling or longitudinal rolling can beaccomplished at the option of the operator; to provide an improvedmachine for effectingI a Vcontinuous cross-rolling;u of the dough, and asubsequent longitudinal rolling thereof; to provide improved mechanismfor delivering` and distributing the dough sheet to a travel-l ling beltconveyor; to providean improved arrangement for quickly and convenientlychanging' or converting the apparatus from a cross-rolling' machine; toa straight or longitudinal rolling machine, or vice versa; to provide anapparatus which shall vbe simple in design and manufacture whilebeingeficient and economical to maintain and operate, and in general `toprovide an improved dough rolling apparat-us of the character referredto. ,y

Certain parts of the machine which: we have selected as illustrative ofspecific application of our invention are in the nature of a modicationor improvement on; the construction shown in Frank M; Peters U; PatentNo. 881,439, for dough sheeting machine, issued March 10,1908. Y

Injlthe drawings of our said machine accompanying` this specification,

Fig. l is a plan view of the principal portion ofthe machine;

Fie'. l2 is an end elevation of the` machine.

Fig. 3 is av section taken onthe line 3 3 of Fig. 2.

Fig. Gis a plan View showing the manner in which the sponge orcross-rolled dough is carried away by the belt conveyor, and

Fig. i' is a view similar to Fig. 6, but showing; the manner in whichthe sweet dough is delivered.

Referring to the drawings, it will be observed that the principaloperating;` parts of the machine are mounted upon a cast iron frame orfoundation designated as a whole 20, such frame 20 comprising a pair oflongitudinal .side members, 2l and 22, and a pair of end members, one ofwhich is indica-ted at 23. The frame is raised from the floor by columnsor standards, for instance, as at 24 and 25.

At one end of the machine a shaft 2G is journaled transversely in thelegs 24, and 2.5, on which shaft there is keyed a drum, 27. At the otherend of the machine is another similarly disposed shaft 28, carrying asimilar drum, 29, and around said pair of drains there is trained a beltconveyor, 50. Said conveyor is driven through the shaft 2S, by thefollowing mechanism:

`A motor, 3l, is mountedbeneath the machine and drives a transv rselyarranged shaft 32, by means of a pair of belt pulleys, 33 and gli,connected by a. belt, 35. Said shaft 33, by means of a pulley, 36, keyedthereto, drives a countershaft 37, throiigh4 a belt 88 and pulley l39,keyed to said countershaft 37. it will be understood that the shafts 32and 37 are journaled in suitable supporters or pedestals which may be.either independently secured to the floor, as shown in 5, or connectedto the frame in any suitable manner.

On the shaft 37, there is keyed abelt pulley, 40, which, by means of abelt, al, drives a pulley, 42, keyed to a transverse shaft, 43,journaled transversely in the frame of the machine. On the opposite endof said shaft 43, there is keyed a bevel pinion, Llei, meshing` withabevel gear 4.4:, keyed tothe end of a longitudinal shaft 45. On theopposite end of shaft l5 there is keyed a bevel pinby the abovedescribed of dough rollers, 46 and 47.

ion 45@L which drives bevel gear 45b keyed on the shaft 28. It will beunderstood. that train of mechanism, the drum 27 and belt 30 carriedthereby may be driven continuously in suoli direction that.

the top stretch ofthe belt moves from left part of which constitutes ahopper, 5l, in

which the batches of dough are introduced 'thickness of the dough sheetby the opera-tor of the machine.

The shaft 49 is stationarily journaledin the' hopper housing 50, whilethe other shaft 48 is carried in a journaled frame as a part of anintegral bracket 52, one at each end of the shaft, said brackets 52being slidably mounted in the housing 50, so that the roll 47 Amay bemoved towards or from the roll 46 whenever it is desired to regulate theformed and delivered by the said pair of rollers. Said rollers areindependently driven by bevel gears, 53 and 54, keyed to the end of theroll shafts 48 and 49, said bevel gears 53 and 54 mesh with a pair ofoppositely disposed bevel pinions and 56, mounted to slide upon, andadapted to be driven by a square shaft 57, fournaled in suitablebearings, as at 5S and 59, and secured to the top of a reetangularswinging frame 60. Said bevel gears 55 Vand 56 are positioned axially,in order to insure correct meshing with the beveled gears 53 and 54, byforked brackets 61 and 62, through the ends of which the shaft 57passes.

lt will be observed that the forked bracket 61 is made as a permanentpart of the lower end of the roll housing 50, while the forked bracket62 is slidable toward or from the bracket 61in order to allow for changein spacing of the rolls. To facilitate said adliustment and to maintainthebevel gears 54 and` 56 permanently in correct mesh, the slidingbracket 52 and the sliding forked bracket 62 are preferably integrallyconnected, or made as a single casting so that they may besimultaneously adjusted. The swinging movement of the frame 6() iseffected by means of a pivotal connection with the main frame, saidpivotal connection comprising a stationary pin or trunnion 61a,projecting upwardly from a bra'cket'62, secured to the side of the mainframe. rlhe frame 60 is formed with an integrall bracket or web 63,having a boss 64,

Vbored out to'accommodate the fixed trunnion 61a. The frame 60 isarranged to swing through an angle of 90 degrees with reference to themain frame, and in a horizontal plane` so that the `aXes of the rolls 46and 47 can be positioned either at right angles to the axis of the beltdrum 27 or parallel therewith.

In the position of the parts shown in Fig. l, the frame 60 is arrangedcrosswise of the main belt 30, with the rolls at right angles to theaxis of the belt drum 27, so that the dough sheet is delivered crosswiseof the belt. In such position the frame 60-is supported upon thefinished upper surfaces of the side frames 2l and 22, axially swingingmovement of said frame being prevented by a lock-pin 65 inserted througha lug 66 in the frame 60 and entering a suitable aperture in the top ofthe side frame 2l. Such is theposition of the swinging frame and rollscarried thereby, when it desired to cross-roll the dough sheet.

`When it is desired tomake sweet dough, in which case it is notnecessary or desirable to cross-roll the material, the frame 60 is swungthrough an angle of 90 degrees into such position that the lock-pin 65(see Fig. l) can be inserted in an aperture 67, in a lug 66 on the sideframe 22, thus bringing the rolls into a position parallel with the beltdrum 27 (as shown in Fig. 5) so that the dough sheet is delivered by therolls to the y belt longitudinally of the latter. n

Ne will nowl describe thefinechanisni for actuating the rolls when theframe 60 is in its different positions. Describing first-the mechanismfor driving the rolls46 and 47 f when they are positioned for crossrolling as in Fig. 1, it will be observed that when the frame is in saidposition, the spur gear 69 which is keyed to the end of shaft 57, is

in engagement with an intermediate gear 70,

which gear 7 O'rotates on a fixed pin 7l at the upper end of a bracket72 formedas an integral extension of the upper portion 74 of theL-shaped standard 73. The upper or horizontal limb of said standardisbolted to the outer end 475 of the bracket 62a in which the pin 6l,ismounted.

In the bracket 72 there is also fixed a pin 76 which carriesianotherintermediate gearv 77, said intermediate gear 771neshing with gear 7()and a large gear 78 keyed on the shaft 43. It is manifest that when themotor is energized, the rolls, when in such crossrolling position willbe driven through shafts 32, 37, 43, gears 77, 70,69, shaft 57, thebevel pinions 55 and 56 meshing with the bevel gears 53 and 54 ontheroll shaft.

Vhen itis desired to arrange the apparatus for lthe rolling of sweetdough, that is to say, dough which does not require crossrolling, thepin 65 is removed, permitting the frame`60 to be swung through an angleof 90 degrees, and then pin 65 is inserted in the locking aperture 67.`kSuch position is shown in Figs. 4 and 5 of the drawings. Then in suchposition, the roll-actuating gear 69 is driven through a train ofintermediate gears 79 and 8O mounted on shafts 81 and 82, carried byswinging arm 83. Said arm is pivoted concentrically with the shaft on abracket 84, the gear 80 lbeing thus always in mesh with spur gear keyedto.

said shaft 45. The arm 83 may be'locked in such position that the gear79 will engage `and mesh with the roll-actuating gear 69. by

means of a bolt 86, which is fixed in the arm 83 and passes through anarcuate slot in the' flange 874 of the bracket 84. It will thus be seenthat when the apparatus is arranged for sweet dough, the actuation oftherolls is effected through shaft 43, bevel pinion 44, bevel gear44?*,vshaft 45, spur gears 85, 80, 79 and 69.

' final rolling-out of the dough sheet to the required thickness. Saidfinishing rolls 88 Aand 89 are mounted on a fixed shaft 90 and anadjustable or slidable shaft 91. The driving of said rolls 88 and 89 iseffected through spur gear-'91 keyed to the shaft 90, said gear 91being' driven by a: mion 92 on a shaft 93. The shaft 93 is journaled inthe legs of the frame and carries belt pulley 94 which is driven fromthe shaft 32 by belt 95 which passes around a belt pulley 96 keyed tosaid shaft 32.

The apparatus also includes kneading roller 97, which is mounted on ashaft 98 journaled in the ends of a pair of swinging` arms 99, said arms99 being` keyed tothe oppositel ends of a. shaft 100, which is journaledyin a pair of brackets 101, mounted on opposite sides of the main frameof `the machine. Said rockshaft is oscillated by means of a downwardlyextending rock arm 101, to the lower end of which there is pirotallyconnected one end of a pitma-n or connecting rod, 102, the other end ofwhich rod is pivotally connected to a crank pin 103 of a. crank 1047keyed tothe outer end of shaft 93.

When the apparatus is arranged for crossrolling as shown in Figs. 1 and2, the hopper housing 51 with its associated rolls 46v and 47, isadapted to be reciprocated cross-wise of the belt, that is to say, in a,direction" parallel with the axes of the belt drum 27. To this end, thehopper housing is provided at its lower end `with a pair ofl flanges,105, and the flange 61, previously described, said flanges beingsupported by two rows of roll ers, as 10G, mounted to rotate freely onpins; 10T, supported at thel same level on opposite sides of the fra-me60. Preferably mi la 'said'. pins 10T have opposite ends fixed inflanges, for instance 108 and 109 projecting upwardly from the frame 60,the rollers rotating freely uponsaid pins, (see Fig, 3), also, in orderto prevent the hopper housing from driving sideways, guide bimcketsl 110secured to the under sides of' the hopper housing. flanges 61 and 105,said brackets 110 fitting between sin s flanges 111 on the sides of saidrollers 10G.

The reciprocating` movement of the hopper housing back and forthcrosswise of the belt along'. the track rolls is effe; ted by means ofthe following mechanism: Referring' to Fig. 5, it will be observed thatspur 112 which is keyed to the longitudinal shaft 45,is arranged to meshwith a drive spur gear 118, keyed to the end of a longit-it dinallyarranged jack sha-ft 11,4, rotatably supported at the one end in thelower end of the bracket 115, the other end of said shaft 114 beingjouinaled in a small bearing 116, 0n one of the legs of the machine. Theouter end of said shaft 114 carries keyed thereto a cani 117, havingformed therein a cam groove, 118, in which groove rolls a cam roll 119,pivotally mounted on a cam rod 120. One end of said cam rod is forked,as shown 121, in order to straddle and be guided by the sli-aft 114, andthe other end of said cam rod 120 is pivotally connected to a pin 122,which is fixed on the rock arm 123, intermediate of the ends thereof.

The lower end of said roz-k arm 123 pivotally mounted on a fined pin124" carried on the end of a small. bracket, 1.24*L bolted to one of thelegs of the machine and the upper end of said rock arm 123 is piv otallyconnected by means of a link 124, with a. spur pinion 125. Said spurpinion 125 rotates onv a pin 128, fixed on the Vend of saidV link 124,-and meshes with a pair of horizontally opposed racks 12T and 128. Therack 12T is stationary and may be formed as a. part of one side of theframe 00, while the other' rack 128 may be formed as a part of orsecured to the under side of the flange 61 of the hopp-er hous Theeffect of the pinion 125 and the racks 12T and 128 is to double theextent of movement. of the hopper housing 50 on the swinging frame G0,with respect to the movement of the rock arm 123. lt will be manifest,that by reason of the -inst-described train of mechanism, the hopperhousing' will make a. complete,v reeiprocation back and fort-h acrossthe belt during each revolution of the shaft 114. i

When it is desired to change the machine from the position shown inFigs. 1 and 2 to the position shown in Figs. 4 and 5, the pin 129 whichforms the connection between the link 124 and the rock arm is removed,permitting link 124 and gear 125 to be detached, thereby preventinginterference with the swinging movement of frame 6() 'whenv the machineis being` changed over.

lt will also be observed that when the machine is in the `position shownin 'Figs l and 2, ior cross-rolling', the arm S3 is swungdown into theposition shown in Fig. 2, so that the gears 79 and 8O are out of the wayand will 'form no obstruction when the frame is being,- swung aroundlfor the purpose ot arrangingthe appa atus for the longitudinal rolling0f sweet dough.

ln some cases it is desired to roll out a sheet ot dough of less widththan the maximum permitted by the dimensions ot 'the i machine. This ismade possible by arranging in the hopper, a movable partition, 130, thelower end of whichis suitably conformed to the curvature ott the rollsd6 and di'. Said partition 13() is secured to the ends ot a set olfsliding rods 131, which pass through suitably bored out bosses 132formed on one side of the hopper lly means oit setscrews 133, thepartition lil() is secured in any desired vposition ol adjustment.

It will be understood that the described details oi construction andoperation are merely illustrative olI a single application or' ourinvention, the scope of which should be determined by reference to theappended claims, said claims being construed as broadly as possible,consistent with the state oi"- the art.
